Gas medium supervision SSIMG

Identification

Function description
Insulation gas monitoring function

Application

Gas medium supervision (SSIMG) is used for monitoring the circuit breaker
condition. Proper arc extinction by the compressed gas in the circuit breaker is very
important. When the pressure becomes too low compared to the required value, the
circuit breaker operation shall be blocked to minimize the risk of internal failure.
Binary information based on the gas pressure in the circuit breaker is used as an

Comment
On
Function must be
Typically no scaling is required
Typically no angle compensation
is required. However here the
required direction of P & Q
measurement is towards busbar
(Not per IED internal default
direction). Therefore angle
compensation have to be used in
order to get measurements in
aliment with the required
direction.
Only UL1L2 phase-to-phase
voltage is available
Typically no additional filtering is
required
